If the camera must be installed in an environment containing dust or other particles,
take required measures to protect the camera unit from dust adhesion.
Do not unplug the cable while power is being supplied to the camera unit. To prevent
product damage, always shut down the power supply before unplugging the power
cable.
When the surface of the camera window becomes dirty due to dust or grime, black
smudges appear in the displayed image. Use an air blower to remove the dust
particles. Dip a cotton swab into ethanol alcohol and clean the camera window. Be
careful not to scratch the glass.
Use of non-infrared lighting such as a fluorescent lamp is recommended. If halogen
lighting is employed, always install an infrared filter into your system configuration.
Please note that exposure to long wavelength light outside of the sensors visible
optical range can affect the image.
Sensitivity may fluctuate depending on the spectral response level of the light source.
In cases like this, changing the light source to one with a different spectral response
level may reduce this problem.
For stabilized image capturing, turn ON the power supply and execute aging for ten
to twenty minutes before actually using the camera unit.
Do not share the power supply with motor units or other devices that generate noise
interference.
The signal ground (SG) and the frame ground (FG) are connected inside the camera
unit. Design the system configuration so that a loop will not be formed by the ground
potential differential.
Do not disconnect the camera while rewriting an embedded memory.
When you change exposure mode that is set at NED factory, input control signal
(CC1) from the capture board.

2.3 Optical Interface
The mount that installs the lens is different according to the model of the camera.
Nikon F mount is prepared as a standard issue, and when 1024 pixels are used,
C mount can be selected.
Notes:
1）Quantities of light and the wavelength etc. of a source of light necessary to take the
image for which the customer hopes are different according to the usage. The factor to
decide these contains physical properties, the speed, the spectrum characteristic of the
object taken a picture of, the exposure time, and the characteristic of the source of light
and the specification etc. of the taking system.
It is a luminous exposure (exposure time × quantities of light) that it is important
because an appropriate image is obtained. Please decide the exposure time and
quantities of light after examining which element the customer values enough.
2) Keep these guidelines in mind when setting up your light source:
LED light sources are relatively inexpensive, provide a uniform field and longer life
span compared to other light sources. However, they also require a camera with
excellent sensitivity.
Halogen light sources generally provide very little blue light but have high infrared
light (IR) proportions.
Fiber-optic light distribution systems generally transmit very little blue light relative
to IR.
Metal halide light sources are very bright but have a shorter life span compared to
other light sources.
3) Generally speaking, the brighter the light sources, the shorter the life span.
CMOS image sensors are sensitive to infrared (IR). We recommend using daylight
color fluorescent lamps that have low IR emissions. If you use a halogen light source,
to prevent infrared from distorting the images use an IR cutoff filter that does not
transmit wavelengths.

3 Hardware
3.1 Camera Connection
Use the camera in the following way:
① Camera Link cables must be used to connect the camera unit with the frame grabber
board.
Notes:
1） Camera Link cables must be used to connect the camera unit with the frame
grabber board.
2） Use asymmetric Camera Link cables and connect the camera with the
connector labeled as ”Camera side”.
3） If there are two connectors in Base Configuration of Camera Link, please after
confirming the specification of a frame grabber board and connect it.
②
Connect the camera with the designated power supply.
Notes:
Use the designated power cable to connect the camera with the power source for the
camera. Insert the plug end of the cable into the camera. Attach the opposite end
(loose wires) to the power unit. Other than those above, a personal computer, a
frame grabber board, a compatible lens, a lens mount, a light source and an encoder
are necessary, depending on the situation.

<Note: Choosing the appropriate Camera Link cable length >
According to the Camera Link Specification, the maximum cable length is 10m. But the
maximum cable length to be able to transfer data depends on the type of cable
performance and clock speed. The actual maximum transmission distance becomes less
than 10m at faster clock speeds, though the transmission distance of 10m is feasible at
slower clock speeds.
The following table shows values being calculated in accordance with the Camera Link
Specification 2007.Version1.2, using a typical cable (14B26-SZLB-xxx-0LC from 3M) and
frame grabber board (Solios from Matrox). Please choose the appropriate Camera Link
cable type and length for your application. We recommend you perform a connection test
in advance.

3.4 Power Supply
The camera requires a single power supply (DC+12 to +15V).
The indicator (LED green) blinks when supplying power, and it will change into
lighting in about two seconds.
Notes:
1) When selecting a power source, choose one with the capacity to allow for inrush
current. (15W or more recommended)
2) Insert the cable plug securely until it locks into position. This is to prevent the
connector from coming loose during power transmission.
3) Turn off the power supply at once when the indicator (LED green) doesn't light
even if supplies power. Make sure that the power supply is used on proper
voltage and capacity and wiring arrangement is correct.
4) It is recommended that the shield processing of the power cable to be connected
with GND on the power supply side.

4 Camera Control
The camera can be controlled through the serial communication. Two methods can
be used to change the camera’s parameters. The first approach is to change
parameters using CLISBeeCtrl (Camera control software). (See “8 CLISBeeCtrl”.) Or
you can also change the parameters directly from your application by using serial
communication commands to set values in the camera register.
Once the camera has been set up according to your requirements, the camera can
be used to read data without need of controlling it via the serial interface.
4.1 Flow of Camera Control
4.1.1 Command Overview
The serial interface uses a simple ASCII-based command.
Communication begins when the computer sends control commands to the
camera.
The camera receives and interprets the computer commands and then executes
control operations accordingly.
Transmission ends when the camera returns the analyzed results of the control
commands to the computer.
Always allow the previous transmission to end before starting the next
transmission. (Only one command can be sent per transmission.)

4.4 Startup
After turning on, the camera run a startup procedure before it starts getting images
and outputting data. It takes about four seconds.
The start-up is executed by the following sequence, and as for the camera, the
preparation for the image acquisition and the output is complete when normally
ending.
(1) The camera hardware initializes. The indicator (LED green) blinks.
(2) Reads out the latest camera settings from the flash memory. (User settings if
any or factory default settings)
(3) Set up the camera with the setting value from the flash memory.
The indicator (LED green) changes from blinking into lighting.

4.5 Saving and Loading Camera Settings
The camera settings data is saved in the internal memory (flash memory) and is
loaded from the memory when turning on the power supply or loading (sending the
“rfd” command).
Commands for rewriting the memory are as follows.
Reset to factory settings (rst)
Store present setup data in memory (sav)
Store pixel correction data in memory (wht)
Notes:
1) The number of times the flash memory can be rewritten will vary depending
on actual operational conditions.
2) After turning on the power supply, the camera always checks the memory
status. When it is content outside a set range due to the breakdown etc., it
automatically rewrites it in the memory setting value when the factory is
shipped.
3) If the camera power is disconnected while rewriting the memory, the whole
data saved in the memory will be deleted.
4) As it takes several seconds to rewrite the memory, do not disconnect power
supply before receiving the answer from the camera.
5) Please do when you change the exposure mode from factory setting with
external trigger signal (CC1) supplied from the frame grabber board side. If
you do not send CC1 or sending control input signals are out of the
designated range, you cannot get images and cannot change the settings.
See 4.8.2 and 4.8.3.

Programmable exposure time (μs) = 1000 ÷ {40 ÷ 2 ÷ 2} =100
Scan rate (μs) = 100 + [{20 + 6} ÷ {40 ÷ 2 ÷ 2} = 102.6
4.8.2 External Trigger Exposure Mode (External trigger edge)
In external trigger exposure mode (Trigger Edge), the exposure time is determined
by the setting through the sireial communication, each exposure starts with the rising
edge and the line period is determined by the time from rising edge to rising edge of
the trigger pulse. The range of programmable exposure time, the timing chart of the
exposure and the readout are shown below.

4.11 Pixel Correction
Generally speaking, image sensors (CCD, CMOS and so on) have fixed pattern
noise and photo response non-uniformity. When you use a lens, lens shadings and
light sources also can cause non-uniformity. The camera is factory set to the optimal
correction before shipping in order to provide images of high grade. The camera also
has a user white correction function in order to cope with lens shading and
non-uniform illumination.
Cal_bl : Output data of each pixel in perfect dark (factory correction)
Cal_wh : Output data of each pixel in uniform illumination (factory correction)
or when viewing a subject for correction (user white correction)
Target_Val : Target value for user correction (10bit output conversion value)
Vin:Input data (Before correction) Vout :Output data (After correction)
The corrected data is expressed by the following equation.
Vout=(Vin-Cal_bl) x Target_val / (Cal_wh-Cal_bl)
Correction target value
Image“before”user arbitrary pixel
is corrected.
Green line is Luminance Profile
Image“after”user arbitrary pixel

NED
4.11.1 How to calibrate the camera
(1) Remove the lens cap and point it at a white illumination, in order to set a uniform
wave level. Then you can acquire arbitrary white correction data. When a lens is
attached, the shading by both the lens and the light source will be simultaneously
corrected. At this time, please defocus to avoid being affected by the non-uniformity of
the object.
(2) Send the “wht CR” command through serial communication.
(3) Confirm that the camera returns “>OK” and “>wht”. This means that arbitrary white
correction data has been saved and loaded onto the camera.
(4) Send the “shc 2, VAL CR” command through serial communication. Then the
arbitrary white correction will be on and set to the correction target value.
Notes:
1) The value “VAL” above should be a numeric value from 0~1023 corresponding to the
user correction target value.
2) If the user correction target value is not set a little higher than the acquired picture
brightness, output will not be full-scale.

5.3 In Operation
(1) Does acquisition time out error occur?
<Cause>
① Captured images are too heavy.
Note:
If there are many filtering processes, the assignments to the driver may be
insufficient.
②The cables are detached from the connector.
Note:
Ensure that the power cable and Camera Link cables are connected to the
camera correctly.
③ Camera Link cables come under the influence of noise when the cables are laid
near a light source inverter line or a power line.
Note:
The personal computer in use may be reset.
(2) Are there dark lines in the direction of vertical scanning on the image?
<Cause>
Dust on the sensor window.
Note:
Dust may come on the sensor window from the inside or the outside of the camera.
Remove the dust with air or a lens cleaner.

6 Sensor Handling Instructions
6.1 Electrostatic Discharge and the Sensor
CMOS sensors are susceptible to damage from electrostatic discharge and can
become defective.
6.2 Protecting Against Dust, Oil and Scratches
The CMOS sensor window is part of the optical path and should be handled like
other optical components with care. If you use the camera in a dusty area, prepare a
dust-proof enclosure. Dust can obscure pixels, producing dark lines on the image.
6.3 Cleaning the Sensor Window
Dust: Can usually be removed by blowing the window surface using a compressed
air blower.
Oil: Wipe the window with a lint-free cloth wiper moistened with ethyl alcohol
carefully and slowly.
